Remember how much fun the
original Thermoengine was? Remember how much fun the original Thermal Integration TI-V77L
was? Double that and then add in a 25mm thick 5000RPM
fan and you have the TI-V77N - which draws so much current TI have
set it up to connect via a Molex pass thru.

If you look at the picture below of this nifty
little unlabeled fan you will also notice it is upside down. The impeller
supports are on top, making it look as though the fan is exhausting air up and
away from the heatsink. Well, that is not what it is doing. Rather, the
blades on the impeller are backwards and the fan is actually sucking in air
and blowing it out the bottom.... where it would seem to normally intake air.

If you're
confused don't worry, so are we. Why is the fan backwards, but
blowing in the right direction? Honestly I have no idea, but I suppose someone
must have figured out that the fan can draw in larger volumes of air, or
produce less noise, or something else. If you know for certain feel free to tell
us.

The
TI-V77N uses the same heatsink as that of the TI-V77L which first made the
rounds some months ago. The only difference between the two is the fan. For most
of use, a smaller and quieter
fan is more of an asset than a noiser fan which improves cooling
factors.

Thanks to
the performance freaks and cooling junkies, a noisy fan like this will produce
some really good cooling results when used on an AthlonXP or other socketed
processor. In general, heatsinks with this type of design have better thermal
results because all the exhaust air is blown down, directly at the heat source.
Other types of heatsinks simply blow this
air out to the sides and it really isn't used as effectively that
way.
